AUTOMOBILE HORN.

Application filed 0etober 19, 1925. Serial No. 63,287.

The present invention relates to improvements in automobile horns or whistles, and its particular object is to provide a horn that is very simple in construction, can be made very economically and sold at a reasonable price. It is particularly proposed to provide a horn that consists of two pieces only, of which one may be driven into the other so that thereby the device is made complete and ready to be secured to the exhaust pipe of a motor vehicle or whatever source of pressure is utilized for producing the sound.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred form of the invention is illustrated in the accompanying drawing in which:

Figure 1 shows a side view of my horn,

Figure 2 a vertical section through one of the members of the same, and

Figure 3 an end view of the latter.

While I have shown only the preferred form of the invention it should be understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

My horn consists in its principal features of a pipe 1 closed at one end as shown at 2 and open at the other end and made of substantial length, it being understood that the length as well as the diameter of the pipe may be changed in accordance with the result desired. Near the open end of the said pipe I provide a cut out 3 formed by a slanting cut 4 intersecting a transverse cut 6 as shown in the drawing.

The second member of my horn is illustrated in Figures 2 and 3, and comprises a tubular member 7 closed at one end as at 8, and open at the other end. This tubular member is adapted to be driven into the pipe 1 and to make a tight fit with the same.

' A collar 9 at the open end of the member 7 arrests the inward motion and the inner face of the collar is threaded as at 11 so as to allow the latter to be screwed to the exhaust pipe of a motor vehicle.

The length of the member 7 is preferably such that its inner end substantially registers with the beginning of the out out 3. The bottom 8 of the member 7 is slotted as shown at 12, the slot being positioned in such a way that when the horn is assembled the slot is substantially aligned with the intersection of the transverse and slanting cuts 6 and 4. A lip 13 may be made to slant forwardly from the bottom of the member 7 above the slot 12 as illustrated in Figure 2, the lip being preferably so arranged as to project beyond the transverse out 6 as seen in Figure l.

The collar 9 is preferably made angular in cross section so as to allow a monkey wrench to be used for manipulating the same.

I claim: V

1. An exhaust horn of the character described, comprising a pipe form-ed with an opening in the surface thereof made by a slanting cut intersecting with a transverse cut and a tubular member adapted for endwise insertion into the pipe and dimensioned to substantially reach the transverse cut, the said member having a slot in the forward end thereof disposed to substantially correspond to the depth of the cut, with a projecting lip extending into the opening.

2. An exhaust horn of the character described, comprising a pipe formed with an opening in the surface thereof made by a slanting cut intersecting with a transverse cut and a tubular member adapted for endwise insertion into the pipe and dimensioned to substantially reach the transverse cut, the said member having a slot in the forward end thereof disposed to substantially correspond to the depth of the cut, with a projecting lip extending into the opening, and with an angular collar at the open end facilitating the fastening of the said member to an object.

In testimony whereof I affix my signature.

ALBERT JOSEPH ROGER.
